Stirring documentary concentrates on the dangerous and often harrowing journey that unsupervised young kids from Central and South America take to illegally immigrate into the U.S. on the tops of freight trains traveling through Mexico. Through interviews with these children who only want to reunite with, or provide for family, a powerful picture of a socioeconomic problem is presented, as they detail a trip that often ends in death or capture. 83 min.
